CHSPE

About the CHSPE (from their website, click on the above link to read the entire document)

The California High School Proficiency Examination (CHSPE) is a testing program established by California law (Education Code Section 48412). If eligible to take the test, you can earn the legal equivalent of a high school diploma by passing the CHSPE. The CHSPE consists of two sections: an English-language Arts section and a Mathematics section. If you pass both sections of the CHSPE, the California State Board of Education will award you a Certificate of Proficiency, which by state law is equivalent to a high school diploma (although not equivalent to completing all coursework required for regular graduation from high school)
